Patented Sept. 24, 1929 UNITED STATES PATENT OFFICE FRANCIS E. ASHTON,OF CHESTER, PENNSYLVANIA, ASSIGNOB. TO ABERFOYLE MANU- FACTURINGCOMPANY, OF CHESTER, PENNSYLVANIA, A CORPORATION OF PENN- SYLVANIASHUTTLE Application filed December 5, 1928. Serial No. 323,817.

This invention relates to weaving and more particularly to an improvedshuttle which is particularly adapted to the form of loom shown anddescribed in my application executed and filed on even date herewith,Serial No. 323,818.

In the loom above referred to, weft thread from a cone is looped overthe pin on the shuttle and passed through the shed of the warp into ashuttle receiver and is then returned to a shuttle receiver on theinitial side on the succeeding pick. It is necessary to then remove theloop of weft thread from the shuttle and to place a new loop thereon foreach successive pair of picks.

The shut-tle herein described is so arranged that the loops of the wovenwefts may be discharged and new loops to be woven received by the pinautomatically and without severing the weft thread at any time.

One of the objects of my invention, therefore, is to provide a shuttlewhich has means for receiving and discharging a loop of weftthread.

Another object of the invention is to provide a shuttle which may beautomatically operated for receiving and discharging a loop of weftthread.

he shuttle which comprises my invention is in outer configurationidentical with the shuttle used in the present day looms. It has a leveroperating in a slot, the slot terminating in a transverse channel andthat end of the lever being provided with a pin. The other end of thelever is depressible for raising the pin to discharge the loop of thewoven weft from the pin and to receive thereon a new loop of weft to bewoven.

The discharge of the loop of weft thread may be assisted by a shoulderformed in the channel while the pin may be normally held in. its loweredposition by means of a spring acting to raise the other end of thelever.

If desired, each end of the shuttle may be provided with a threadreceiving and discharging pin, each on the outer end of a pivoted lever,and the other ends of the levers may slightly overlap at a point in thecenter of the shuttle so that both ends may be depressed in the mannerjust above described.

The drawings illustrate embodiments of the invention and the viewstherein are as follows:

Figure 1 is a front elevation of the shuttle,

Figure 2 is a top plan view,

Figure 3 is a longitudinal section on the line 33 of Figure 2,

Figure 4 is a crosssectional View on the line 1-4 of Figure 2, lookingin the direction of the arrows,

Figure 5 is a front elevation of a double ended or universal shuttle,

Figure 6 is a top plan view of the same,

Figure 7 is a longitudinal section on the line 7-7 of Figure 6, and

Figure 8 is a cross-sectional view on the line 88 of Figure 6, lookingin the direction of the arrows.

ljigures 1, 2, 3 and 4 represent a shuttle which may be used for weavingthe weft into the cloth on a machine such as that described in myapplication for loom, above mentioned.

That particular loom therein shown is what is known as a left hand loom;and for use with a right hand loom, the entire mechanism of Figures 1,2, 3 and 4 would necessarily have to be reversed or the shuttle shown inFigures 5 to 8 used.

The shuttle proper has a wooden body 11 and pointed steel ends 12.Between the body and the steel ends is the usual fibre plate 13. Thefront face of the shuttle is provided with a longitudinal groove 1 1 andnear the left hand end of the shuttle a channel 16 passes transverselythrough the shuttle.

At the outer end of this transverse channel is an undercut groove 17which provides a shoulder 18. The left hand end of the groove 1% is cutback a considerable distance, as shown at 19 in Figure 2, and alignswith the undercut groove 17.

The body is provided with a longitudinal vertical slot 21 which extendsinto the channel 16 and into an enlarged recess 22 which extendsequi-distant from the transverse center of the body. A lever 23 ispivotally mounted at 24: in the slot 21 and its outer end terminates ina downwardly extending pin 26 whose end normally rests in a slightdepression 27. This pin is in close vertical proximity to the shoulder18 and is substantially in alignment with the cut out end 19 of thegroove 14 so that when thread is passed into the shuttle by means of theneedle of the loom entering the channel 16, it will pass behind thesmall depression 27 to be caught by the needle when it is lowered.

On the transverse center of the body and of a diameter equal to thewidth of the re cess 22 is a circular hole 28 into which is placed aspiral spring 29 which exerts an upward pressure on the inner end of thelever 23 so as to normally hold the pin 26 in the depression 2?.

The slot 21 may extend entirely through the body at 31 and that part ofthe slot beneath the recess 22 may be closed by a plug or plate 32pinned into the body by the pins 33 or, the plate 32 may be entirelydispensed with and that portion left integral with the body.

It is intended that when pressure is placed on the lever 23 at a pointsubstantially above the spring 29 the said spring shall be depressed,thereby pivoting the lever on the point 24 (which may consist of thebolt, as shown in Figure 2), and thus raising the pin 26 sufficientlyhigh that its lower end will be substantially in alignment with theshoulder 18. This will shed the woven weft loop from the pin and whenthe needle enters the channel 16, the new weft thread will be laidbehind the pin 26.

Figures 5 to 8 inclusive show offset slots 41 and 42 for receiving aleft and right hand lever 43 and 44, which said levers are identicalwith the lever 23 shown in Figures 1 to 4 inclusive.

In this form of shuttle, the recess 46 will of necessity be wider thanthe recess 22 shown in the former figures because the inner ends of boththe levers 43 and 44 will rest above the spiral spring 47 and the pins48 and 49 on the outer ends of the levers will be simultaneously raisedby pressure placed on the adjacent inner ends of said levers.

The right hand outer end. of the shuttle shown in Figures 5 to 8 isidentical with the left hand end of the same and with the left hand endof the shuttle shown in Figures 1 to 4.

The form of shuttle shown in Figures 5 to 8 may be universally used withleft and right hand looms and may be used in a loom where exceptionallywide cloth is being woven and where the loops must be shed on each sideof the warp and a new loop placed alternately on the pins.

The shuttles illustrated in the drawings are susceptible of variousmodifications and changes without departing from the invention hereinset forth and hereafter claimed.
